In June 2013, Embraer has launched the second generation of its E-Jet family of commercial aircraft, the E-Jets E2, which comprise three new versions, the E175-E2, E190-E2, and E195-E2.

The E190-E2 is expected to enter into service in the first half of 2018. The other variants will follow in 2019 (E195-E2) and in 2020 (E175-E2).

On-board with three product lines

Embraer selected Liebherr-Aerospace as the supplier of the advanced high-lift system, the integrated air management system, the nose wheel steering control module, as well as the leg strut and trailing arm for the main landing gear.

High-lift system

The high-lift system features a complete fly-by-wire control system with dual channel skew detection. The system includes integrated computers, highly reliable hydraulic and electro-mechanical actuators and power control units.

Air management system

The air management system features integrated control architecture with the latest technologies in terms of lightweight electro-pneumatic and mechanical components. It includes the engine bleed air system, the air conditioning system and the cabin pressure control system. The systems feature a very high level of control integration, with superior features to improve the passenger comfort (e.g. multi zone thermal environment management, cabin pressure smooth control), as well as the latest technology to minimize the air system related engine fuel burn.

Nose wheel steering control module

The nose wheel steering control module is a computer module that allows steering the aircraft’s nose landing gear when the aircraft is taxiing. The module will be adapted from the current landing gear system of the first E-Jet generation developed by Liebherr-Aerospace.

Leg strut and trailing arm

Liebherr-Aerospace will manufacture the landing gear components according to the drawings by ELEB*, which is responsible for the E175-E2 main landing gear design. The trailing arm will be made of titanium, the leg strut of steel.

*ELEB Equipamentos Ltda. ("ELEB") is a wholly-owned Embraer subsidiary located in São José dos Campos which produces and sells precision hydraulic and mechanical equipment for the aviation industry, mainly for Embraer aircraft.
